ABSTRACT

In the present work, we prepared the MWCNT-L-POSS from the grafting reaction between octa (propylglycidyl ether) polyhedral oligomeric silsesquioxane (POSS) and multi-wall carbon nanotubes (MWCNT). The certainty of this product was confirmed by using the Fourier-transform infrared spectroscopy (FTIR) technique. The MWCNT-L-POSS was applied as an additive for epoxy resin which was cured at room temperature. The main behaviors of the fabricated composite were studied including flexural strength and flammability. The flexural strength increase by 24.8% from 86.8 to 108.3 Mpa. The flame retardant of epoxy resin was improved by adding MWCNT-L-POSS with reducing the value of total smoke release (TSR), total heat release (THR), and peak heat release rate (PHRR).

摘要

在目前的工作中，我们通过八（丙基缩水甘油醚）多面体低聚倍半硅氧烷（POSS）和多壁碳纳米管（MWCNT）之间的接枝反应制备了 MWCNT-L-POSS。使用傅里叶变换红外光谱 (FTIR) 技术确认了该产品的确定性。MWCNT-L-POSS 被用作环氧树脂的添加剂，环氧树脂在室温下固化。研究了制备的复合材料的主要行为，包括弯曲强度和可燃性。抗弯强度由86.8Mpa提高到108.3Mpa，提高了24.8%。MWCNT-L-POSS的加入提高了环氧树脂的阻燃性，降低了总烟气释放量（TSR）、总放热量（THR）和峰值放热率（PHRR）值。
